Background: Treatment of skull base tumors is challenging due to limited access and presence of important neurovascular structures nearby. The success of a complete tumor resection depends on the extent of tumor exposure and secure field of view. While these tumors are often removed by transcranial endoscopic access, transfacial approach is sometimes required depending on the location and size of the tumor. This study describes various transfacial approaches in patients undergoing skull base tumor resection. Methods: From March to November 2013, 15 patients underwent skull base tumor resection via transfacial accesses at a tertiary institution. Data were reviewed for patient demographics, type of access used, completeness of tumor resection, surgical outcome, and postoperative complications. Results: Two clivus tumor patients underwent transmaxillary approach; three tuberculum-sellae and suprasellar-hypothalamus tumor patients underwent transbasal approach; three clinoid and retrobulbar intraconal orbital tumor patients underwent orbitozygomatic approach; and seven petroclival-area, pons, cavernous sinus, and lateral-sphenoid-wing tumor patients underwent zygomatic approach. In all cases, the upper and lower margins of the tumor were visible. Complete tumor removal consisted of 10 cases, and partial tumor removal in 5. There were no immediate major complications observed for the transfacial portion of the operations. The overall cosmetic results were satisfactory. Conclusion: Plastic surgeons can use various transfacial approaches according to the location and size of skull base tumors to secure a sufficient field of view for neurosurgeons.

For efficient compatible system between medical clinics, the medical information has to be built on a standardized protocol such as a HL7 for text data and a DICOM for image data. But it is difficult to exchange information between medical clinics because the systems and softwares are different and also a structure of data and a type of code. Therefore we analyze a structure of DICOM file and design an integrated database for effective information sharing and exchange. The WISD system suggested in this paper separate the DICOM file transmitted by medical clinics to text data and image data and store it in the integrated DB(database) by standardized protocol respectively. It is very efficient that each medical clinic can search and exchange information by web browser using the suggested system. The WISD system can not only search and control of image data and patient information through integrated database and internet, but share medical information without extra charge like construction of new system.

Background: Dynapenic obesity and sarcopenic obesity increase cardiovascular disease (CVD) and mortality in nonuremic patients. The present study was designed to determine the prevalence of dynapenic obesity and sarcopenic obesity and their associations with CVD risk factors in peritoneal dialysis (PD) patients. Methods: All eligible PD patients in Tehran peritoneal dialysis centers were included in this cross-sectional study. Skeletal muscle mass and fat mass were assessed using bioelectrical impedance analysis. Muscle strength and physical performance were determined using hand grip strength and a 4-meter walk gait speed test, respectively. In addition, a 5-mL blood sample was obtained from each patient. Results: The prevalence of dynapenic obesity and sarcopenic obesity were 11.4% and 3.8% in PD patients, respectively. Serum high-sensitive C-reactive protein (hs-CRP), soluble intercellular adhesion molecule type 1, triglyceride, total cholesterol, and low-density lipoprotein cholesterol were significantly higher in PD patients with dynapenic obesity than in dynapenic nonobese and nondynapenic nonobese patients. Similarly, serum concentrations of CVD risk factors in PD patients with sarcopenic obesity were higher than in nonsarcopenic nonobese patients, but these differences were statistically significant only for serum hs-CRP and triglyceride. In addition, muscle strength and skeletal muscle mass percentage were negatively associated with markers of inflammation and dyslipidemia, whereas body fat percentage was positively associated with these CVD risk factors. Conclusion: This study indicates that although the prevalence of dynapenic obesity and sarcopenic obesity are relatively low in PD patients, these disorders may be associated with CVD risk factors.
Background: Pertussis is highly contagious respiratory disease. Healthcare workers (HCWs) can be an important mediator of the disease. A seroprevalence of pertussis was investigated in HCWs to determine the immune status against pertussis and to detect the unidentified pertussis. Methods: This study was conducted for HCWs at a hospital located in Korea in 2011. After obtaining written informed consent for HCWs voluntarily participating in the study, 10 mL of blood was collected from each subject. Demographic and medical data were collected using questionnaire. Data on the underlying disease and vaccination history were reviewed again through medical records. The presence of anti-pertussis toxin (anti-PT) immunoglobulin G (IgG), and immunoglobulin A (IgA) was detected by quantitative analysis using a commercially available ELISA kit (EUROIMMUN, $L{\ddot{u}}beck$, Germany). Results: A total of 412 HCW participated in the study. Among them, 14 were excluded due to the inadequate sample amount or medical history not secured. Of the 398 HCWs analyzed, 16.6% (66/398) were men and the mean age was $33.82{\pm}9.10years$ (range, 21-67). The mean anti-PT IgG titer was $8.32{\pm}20.40IU/mL$ (range, 0.4-287.5 IU/mL). The overall seroprevalence (rate of anti-PT IgG antibody [Ab] titer > 5 IU/mL) was 33.7%. Three (0.8%) HCWs had the Ab level > 100 IU/mL indicated acute infection. There was no statistically significant difference in the seroprevalence and mean titer of anti-PT IgG Ab according to age group, type of occupation, patient-facing position, or working in the pediatric department. Conclusion: The seroprevalence of pertussis of the HCWs of a university hospital in Korea was low, and there were some unrecognized acute infections. Therefore, booster immunization of pertussis to HCWs should be actively considered.

Background: Primary hyperoxaluria (PH), a rare inborn error of glyoxylate meta bolism causing overproduction of oxalate, is classified into three genetic subgroups: type 1-3 (PH1-PH3) caused by AGXT, GRHPR, and HOGA1 gene mutations, respectively. We performed a retrospective case series study of Korean pediatric patients with PH. Methods: In total, 11 unrelated pediatric patients were recruited and their phenotypes and genotypes were analyzed by a retrospective review of their medical records. Results: Mutational analyses revealed biallelic AGXT mutations (PH1) in nine patients and a single heterozygous GRHPR and HOGA1 mutation in one patient each. The c.33dupC was the most common AGXT mutation with an allelic frequency of 44%. The median age of onset was 3 months (range, 2 months-3 years), and eight patients with PH1 presented with end stage renal disease (ESRD). Patients with two truncating mutations showed an earlier age of onset and more frequent retinal involvement than patients with one truncating mutation. Among eight PH1 patients presenting with ESRD, five patients were treated with intensive dialysis followed by liver transplantation (n=5) with/without subsequent kidney transplantation (n=3). Conclusion: Most patients presented with severe infantile forms of PH. Patients with two truncating mutations displayed more severe phenotypes than those of patients with one truncating mutation. Sequential liver and kidney transplantation was adopted for PH1 patients presenting with ESRD. A larger nation-wide multicenter study is needed to confirm the genotype-phenotype correlations and outcomes of organ transplantation.
Background: Radiation therapy (RT) is frequently used for supportive treatment and management of advanced head and neck cancers. This study performed a retrospective review of the treatment methods that were used for intractable draining fistulas in seven patients who had received RT for head and neck cancers. Treatment methods used for two of the seven patients are presented in detail. Methods: From 2009 to 2020, seven patients underwent reconstructive surgery for intractable fistulas which occurred after RT for head and neck cancers. Patient characteristics, medical history, treatment method, and treatment outcome were reviewed for each case. The type of surgery performed, failure rate, and treatment period were also analyzed. Results: In this study, a total of seven patients received additional management for radiation-induced fistulas. Patients underwent a mean of 3.3±1.4 surgeries (maximum: six surgeries) to resolve their fistulas. The mean time interval from the first surgery to the last surgery for the patients to achieve resolution of the fistula was 8.7 months. Loco-regional flaps have performed an average of 1.9±1.5 times. However, all loco-regional flaps failed. Instead, the patients' intractable fistulas were resolved with the use of distant flaps or free tissue transfers. Conclusion: Fistulas that develop after head and neck cancer treatment following RT are difficult to treat with simple loco-regional flap procedures. Therefore, more aggressive treatment techniques, such as distant flap or free tissue transfer, may be needed to shorten patients' treatment periods and avoid unnecessary surgeries.
Objectives: This study considered the effectiveness of integrative Korean medical treatment for stress-induced hypertensive patients without the use of conventional medication. Methods: A 62-year-old female with stress-induced hypertension (HTN) was hospitalized for 33 days. Her pattern identification was ascendant hyperactivity of liver yang (Ganyangsanghang)-type HTN. Herbal medicine and acupuncture were used for the treatment: Cheonggansoyo-san for 33 days and Chunwangbosim-dan for 15 days, together with acupuncture for 20 minutes twice a day. Blood pressure was checked daily during hospitalization with a digital sphygmomanometer in the brachial artery. Results: After 33 days of treatment, blood pressure decreased. The Handicap Inventory (DHI) scale and Pittsburg Sleep Quality Index (PSQI) scores both decreased. The patient also reported fewer complaints. A five-month follow-up after discharge, with no further treatment, confirmed stable blood pressure. Symptom improvements continued with no significant side effects. Conclusions: This study indicates that Korean medical treatment is effective for stress-induced hypertensive patients.

Background: Primary pulmonary malignant mesenchymal tumors are rare, constituting only 0.4% of all lung cancers. Since sarcomas are chemo/radio-resistant, surgical resection is the optimal treatment choice for patients with suitable medical conditions and tumor stage. In the present study, we analyzed the surgical outcomes and survival of primary pulmonary malignant mesenchymal tumors treated surgically. Methods: We retrospectively examined the records of patients with primary pulmonary malignant mesenchymal tumors who underwent surgical resection at our department between January 2010 and December 2020. Patient data were analyzed according to age, sex, tumor grade and stage, resection completeness, surgical type, and tumor histopathology. Results: Twenty patients were included in the study. There were 13 men (65%) and 7 women (35%). The median survival rate was 36 months (range, 19-53 months), and the 5-year overall survival rate was 37%. Unfavorable prognostic factors for overall survival included parietal pleural invasion (p=0.02), high tumor grade (p=0.02), advanced tumor stage (p=0.02), and extensive parenchymal resection (pneumonectomy and bilobectomy, p=0.01). The median length of disease-free survival was 31 months (interquartile range, 21-41 months), and the 5-year disease-free survival rate was 32%. The most unfavorable prognostic factors for recurrence were parietal pleural invasion (p=0.02), high tumor grade (p=0.01), and tumors requiring lung resection with chest wall resection (p=0.02). Conclusion: Primary malignant mesenchymal lung tumors are aggressive and have a high mortality rate. However, acceptable overall and disease-free survival rates can be obtained with surgical therapy.

BACKGROUND/OBJECTIVES: While plate waste has been widely investigated in hospitals, there have been minimal studies specific to the texture-modified diet (TMD). This study aims to determine the percentage of plate waste among patients prescribed with TMD and its contributory factors. SUBJECTS/METHODS: This was a single-centre study conducted in the university hospital on three types of TMD (blended diet, mixed porridge, minced diet) during lunch and dinner meals. Weighing method and visual estimation method assisted by digital photograph were adopted in this study. Face to face interview was carried out to investigate on 1) the food/food service quality factors in terms of patients' satisfaction level towards sensorial quality of food and food services provided and 2) the clinical/external factors including appetite, the provision of oral nutrition support, time taking the diet, the need for feeding assistance and the length of hospital stay. RESULTS: The mean percentage of overall plate waste of 95 patients receiving TMD was high (47.5%). Blended diet was identified as the most wasted diet (65%) followed by minced diet (56%) and mixed porridge (35%). Satisfaction level among patients was moderate. Patients on TMD in general had higher satisfaction level on the aspect of food service as compared to food quality. Substantial association between sensorial qualities of food and plate waste were varied according to individual TMD type. A multiple linear regression showed that only the satisfaction level toward the aspects of appearance and variety of foods were the predictors of TMD plate waste (R2 = 0.254, P < 0.05). CONCLUSIONS: A significant relationship between the percentage of plate waste and the overall satisfaction level of patients receiving TMD suggests that vigorous strategies are needed to reduce the food waste of TMD which will lead to a better nutritional status and clinical outcomes among the patients.
